[Solved] 32bit container on 64bit system with systemd-nspawn.

How can someone install such a thing. Is it possible??

The wiki gives an example but no mention of architectures.

Also since the container works as root will it cause trouble if i try to build software packages on it??

I'd have thought you would setup a 32-bit chroot environment, or am I mistaken? For the chroot case, you have: setarch i686 arch-chroot mnt /bin/bash

~~I'd like to say you could do something similar.~~

MAN PAGES TO THE RESCUE. Apparently, there is the following flag:

--personality=

Yes i saw that. How the packstrap command is going to know that it must install a 32bit base in the directory. I thought the --personality=x86 is for booting.

I think you can use the instructions on building 32 bit packages in a 64 bit environment to set-up the 32 bit chroot, changing the locations to where you want the chroot. That way you'll install a 32bit base.

Yes i know that already. That is a secondary issue which i could also solve by installing a 32bit VM in Vbox. The 32bit on 64bit with nspawn is what i want to do. I am curious.

Ok i think i found something.

Pacstrap lets you use a different config file for pacman with the -C option. So will something like:

pacstrap -i -c -d -C pacman.conf ~/Arch32_cont base
systemd-nspawn -bD --personality=x86 ~/Arch32_cont

work if i set Architecture = i686 in the pacman.conf file??

Just in case anyone needs that.

To create a 32 bit container on a 64 bit system the procedure is.

Copy your /etc/pacman.conf to your home directory and change the Architecture = auto to Architecture = i686

mkdir Arch32_cont
sudo pacstrap -i -c -d -C pacman.conf ~/Arch32_cont base
sudo systemd-nspawn --personality=x86 -bD ~/Arch32_cont

login as root with no password. Do whatever you want (create a user, build packages etc) and you can simply delete everything with:

sudo rm -rf ~/Arch32_cont

This was perfect except 32 repos are elsewhere now. So to make this pacstrap work you need to edit /etc/pacman.d/mirrorlist and add there at least one server from https://archlinux32.org/mirrorlist/ and to install a 32 bit keyring from AUR https://aur.archlinux.org/packages/archlinux32-keyring
